Why open source?
-Open source impossible to avoid, Gartner says”, Network World
-http://www.networkworld.com/news/2007/092007-open-source-unavoidable.html
It’s “impossible to avoid”
Gartner 2007 Study:
By 2011, 80% of all commercial software will contain open source code
Forrester 2008 Study:
Study of 2,252 North American and European Software decision makers
done by Forrester: 66% are interested in open-source software….
Open source seems to be a tactic for achieving the high priority
initiatives.
..
Web 2.0 technologies (such as blogs, wikis and RSS) and
Service Oriented Architecture among their major software initiatives.

30. What is open source ?

31. Open Source Workshop 31
What Is Open Source?
 open source refers to software that is published under licenses that
defines how source code can be made available to everyone to
inspect, change, download, and explore as they wish.
 Open source is not a software methodology
 It is a way of developing ideas and software collaboratively in the open
 Open source is about software license
 Defines how the developers develop the software
 Defines how the users consume the software and contribute back
 Defines how the community interacts with one another

32. Open Source Workshop 32
What characterizes an open source?
 The community of software users and developers interested to
develop some idea in the open create the open source project
 The makeup of each open source project is identified by it’s philosophy, it’s
culture and it’s character defines an open source project.
 Community Philosophy: The software license used for the open source
project captures defines its philosophy
 Community Culture: Where the open source project is hosted can define its
community culture. For example Apache promotes a different culture than
Eclipse.
 Community Character:
 Each project can run differently even within a given open source embodiment.
The community decides on how to create, build and maintain the project.
 The technology offered by a project can also form the character of the project.
For a project that develops applications will be different than one that develops an
infrastructure.

33. Open Source Workshop 33
Open Source License
 License defines the community philosophy
 open source refers to software that is published under licenses that defines how
source code can be made available to everyone to inspect, change, download,
and explore as they wish.
 There are upward of 71 open source licenses which fall into 3
families:
 Give me credit
 Give me fixes
 Give me everything

34. Open Source Workshop 34
Open Source License Type – Give Me Credit
 Examples: AL, BSD, MIT
 Typical Characteristic:
 Derivatives can sub-license
 May have some conditions
 No warranty
 Credit to original authors required
 Limited control by any one entity
 Allows for commercial product development
 Allows for competing services

35. Open Source Workshop 35
Open Source License Type – Give Me Fixes
 Examples: Mozilla (MPL), Eclipse (EPL/CPL), LGPL
 Typical Characteristic:
 Single entity control, still ‘business friendly’. If you modify the code, you need to
make the modification available
 File or derivative based conditions
 Original author may have special rights
 Differentiate between source and binary
 Larger works can be under a different license
 Encourages incorporation of code into larger works
 Ensures direct development benefits all

36. Open Source Workshop 36
Open Source License Type – Give Me Everything
 Examples: GPL (GNU General Public License )
 Typical Characteristic:
 Also referred to COPY LEFT. If you use it, everything must be under this license
 Derivative works remain under the license
 Linked works may also remain under the license
 Ensures all ‘down stream’ have the same rights
 All direct development is contributed back
 Contributors assured code remains open source
 Encourages a full free software economy
 Copyright holder retains much control
 Limits commercial adoption: Forbids distribution for profit
 Software with this type of license cannot be included in Apache
projects

37. Open Source License Type – Give Me Everything
• GNU AGPL v3.0
 “AGPL fixes this “loophole” in GPL by saying that if you use the software over a
network, you are bound by the copyleft. Other than that, the license is virtually the
same as GPL v3.”
• What does it mean ?
 it is never required that applications are published/released.
 The copyleft applies to internal AGPL Software, meaning that changes to these
software needs to be published even though they have never been
published/released and are only used internally.

38. Open Source Workshop 38
Open Source: Most common Licenses
 Apache License, 2.0
 BSD licenses
 GNU General Public License (GPL)
 GNU Library or "Lesser" General Public License (LGPL)
 MIT license
 Mozilla Public License 1.1 (MPL)
 Common Development and Distribution License
 Eclipse Public License
 Artistic Licenses

39. Open Source Workshop 39
License Compatibility
 License compatibility refers to the problem with software licenses
which can contain contradictory requirements, rendering it
impossible to combine code from such packages in order to create
new software packages.
 Let’s consider the following scenario:
 Code distributed with license A says :"modified versions must mention the
developers in any advertising materials“
 Code distributed with license B says : "modified versions cannot contain additional
attribution requirements"
 These two licenses are considered license-incompatible. If
someone combine a software package which uses license A, with a
software package which uses license B, it would be impossible to
distribute the combination because the two requirements cannot be
simultaneously fulfilled.
License Compatibility (wikipedia): http://en.wikipedia.org/wiki/License_compatibility

43. Open Source Workshop 43
Open Source Project Hosts
 Project umbrellas host the open source projects and can influence
the overall culture of a community
 Hosts provide infrastructure for open source project referred to as
PRIM:
 P (portal), R (repository), I (Issue tracking), M (mailing list)
 Can provide legal governance
 There are three main types of public open source hosts:
 Pure infrastructure
 Vendor collaboration
 Community focused

44. Open Source Workshop 44
Project Host Type 1: Pure Infrastructure
 Examples: SourceForge, CollabNet, Codehaus, googlecode, github
 Provide the infrastructure
 Sets overall rules (e.g. type of license permitted)
 Each project governs itself
 Often many small projects
 One or two developers, although may have lots of users
 Fairly small codebase
 Provide an incubator role
 Projects start under incubation and move to a more formal community when they
grow

45. Open Source Workshop 45
Project Host Type 2: Vendor Collaboration
 Examples: Eclipse, ObjectWeb, Mozilla
 Allows companies to collaborate
 Specifically acknowledge the role companies have
 Consider corporate needs
 Closer to commercial software development roadmap
 More planning and oversight
 (e.g.) have a architectural steering committee
 (e.g.) have an official project management committee
 Can be more conservative
 Eclipse recently created “Eclipse Project Incubator” as a place for
innovation and investigation of new and alternative ideas.

46. Open Source Workshop 46
Project Host Type 3: Community Focused
 Example: Apache Software Foundation
 Non-profit corporation
 No staff, all volunteer
 Elected membership
 Primary goal is to foster open source communities
 Provide technical infrastructure
 Provide legal oversight
 Projects start under incubation and once they demonstrate they can run as a
healthy Apache type project they graduate into an Apache top level project.
 Technocratic Meritocracy
 People earn status by what they do
 Project communities are very independent
 Project Management Committee (PMC) is a legal construct
 Binding decisions e.g. to release software
 Community decides direction and priorities

47. Open Source Workshop 47
Examples of Open Source projects
 Apache
 Web Server
 Community initiated (apache.org)
 Linux
 Operating System kernel
 Individual initiated (Linus Torvalds)
 Eclipse
 Universal Integration platform
 Extensible application framework
supporting solution based plug-ins
 IT Vendor initiated (IBM and
others)
 Mozilla
 Browser and client technology
 Hybrid (Netscape + community)

48. Open Source Community
Heart of an open source project
Open Source Workshop 48

49. Open Source Workshop 49
Traditional Commercial Software
 Separate User and Developer Community
 Feedback provided through Beta and early adaptor programs
 Agile development model can help to provide more frequent
feedback
USERS
“use the software”
DEVELOPER
S
“produce
the
software”

50. Open Source Workshop 50
Mixed Commercial – Share Code
 Code Is developed in the open and can be used readily
 Users provide feedback, but can’t modify the main repository
 Software is typically not free or a more advanced form of it is
licensed

51. Open Source Workshop 51
Open Source – Collaborative Environment
 Code Is developed in the open and can be used readily
 Users can become involved in the development of the software
USERS
“use the software”
DEVELOPERS
“produce
the
software”

52. Open Source Workshop 52
Start of an Open Source Project
 Open Source projects typically start with
 A smaller developer community who have an idea to develop
 One or more users who can use the software
USERS
DEVELOPER
S
“produce
the
software”

53. Open Source Workshop 53
Who are the developers?
 A group of people interested to develop some idea in the open
collaboratively.
 Because ..
 They want to create software that solves their business problems
 Want to test new ideas in the market
 Want To participate in new technology development
 Want To test validity of standards through collaboration with users
 Maybe they get paid by an employer, it’s their job.
 Maybe it is just interesting to get involved in new technology!
 Participation in a successful project can open the door to fame and recognition
 …….
 There is no magic answer. This makes it good challenge to analyze how to attract developers for each
project
 IMPORTANT: Anyone interested can join in to help with the
development
 No invitation is required! Just get involved in what is interesting to you and share your
thoughts with the community.
 People from different backgrounds participate in open source. The key is to not be shy
about not having a high command of a given language. Source Code and technology
ideas become the common language.

54. Open Source Workshop 54
Open Source Project
 Open Source Brings Users and Developers together to
 Invent, develop, share experience, improve
 Overtime, users join the developers community to influence what they use (care
about).
USERS
“use and

59. Open Source Workshop 59
Attractive Code Qualities for Starting OS projects
 Directly used by and useful to developers
 Builds
 Follows common standards where applicable
 Modular and flexible
 Consistent
 Enough documentation to help new developers to get started
 Enough test examples to help new developers to get started and be confident to test
their changes
 Can be improved
 Does not have to be functionality complete (Tough concept to grasp)
 Incremental, smaller checkins accompanied with discussions with the community get the community more involved and
enables others to participate in building the software.

60. Open Source Workshop 60
Communication Infrastructure
 Source code repository
 Issue Tracking
 Defines how problems can be reported.
 Provide a way to organize handling of many different ideas, feedbacks, etc.
 Website
 First impression of the project is from the website. It is important to have a good website
which clearly states objectives and introduces the visitor the to project
 Most developers don’t find this a fun thing to do! Find ways to make it happen.
 Documentation
 User documentation : Focuses on how to use the project
 Developer documentation: Focus on how to get involved
 Caution: ‘code talks’ does not work 100%. It is worth to spend time to share information
 Mailing list, newsgroup, or forum
 Communication should be open
 Engages everyone and solicits new ideas and participation
 Communication should be archived
 Archived information can be used to search for problems that were discussed before
 Provides a reference for decisions that were made

61. Open Source Workshop 61
How to attract a community?
 Good product and frequent releases
 Good documentation
 Examples of how to use the software
 Modular and flexible
 Lowers the barrier to entry for developers. Let’s them focus on areas that they are interested
in
 Facilitates adoption by allowing users to pick and choose what they need. Lower footprint.
 Have an open, inviting environment
 Mentor new people to learn the project and feel comfortable to contribute
 But, that’s not enough!
 People need to know about your project to download and use it or come to the site to
participate.
 Talk about the project and how it solves the given business problem through Conferences, Forums,
Articles, …

62. Open Source Workshop 62
Summary
 Open Source brings Users and Developers from all around world
together to invent, develop, share ideas, …
 Community is the heart of Open Source
 Community = stability
 Starting and growing of an open source project requires
 Code
 Infrastructure
 And, dedication and effort to build the community

63. The Apache Software Foundation
The State of the Feather

64. The ASF
 What is the ASF ?
 What does the ASF do ?
 Name some ASF projects you know ?
 Have you used/contributed to the project ?

65. The ASF
➡ ASF == The Apache Software Foundation
➡ Before the ASF there was “The Apache Group” (~2006)
➡ But we needed a more formal and legal entity
➡ The ASF was incorporated in 1999
➡ Governed solely by members - 100% member based entity

66. The ASF
➡ Non-profit corporation founded in 1999
➡ 501( c )3 public charity
➡ Volunteer organization (The ASF doesn’t pay anyone to work on
Apache projects)
➡ Virtual world-wide organization - Membership of Individuals
➡ Exists to provide the organizational, legal, and financial support for
various OSS projects - let the developers develop

67. The ASF
April 13, 1999 - The first official meeting of the Apache Software Foundation (not pictured).

68. The ASF
 Why call ourselves Apache ?
 No, it isn’t an attack helicopter
 A Patchy Server? Nope, that’s just a pun.
 A reference to our development philosophy:
“Characteristic of both Eastern and Western Apache, with the exception of the
Kiowa Apache, was the lack of a centralized tribal organization. The band, an
autonomous collection of small local groups within a given locality, was the
primary political unit as well as the primary warring and raiding unit. The
strongest headman of the local groups was recognized as an informal chief, and
several bands might be united under one leader. Chieftainship was thus not
generally hereditary.” Encyclopaedia Britannica

69. At the start
➡ There were only 21 members
➡ And 2 “projects”: httpd and Concom
➡ All servers and services were donated

70. Today...
➡ We have 468 members...(!)
➡ and 59 emeritus member
➡ >100 TLPs
➡ >30 Incubator podlings
➡ 36 Labs
➡ 16 in the Attic
➡ Tons of committers (literally)
➡ (Over 3000 people)

71. Apache Mission
 Provide open source software to the public free of charge
 Provides a foundation for open, collaborative software development
projects
 supplies hardware
 Supplies communication, and business infrastructure
 Create an independent legal entity to which companies and
individuals can donate resources and be assured that those
resources will be used for the public benefit
Open Source Workshop 71

72. The ASF’s Mission
 Provide a means for individual volunteers to be sheltered from legal
suits directed at the Foundation’s projects
 Protect the ‘Apache’ brand, as applied to its software products, from
being abused by other organizations
 Provide legal and technical infrastructure for open source software
development and to perform appropriate oversight of such software

73. Vision Statement
➡ The Apache Software Foundation provides support for the Apache
community of open-source software projects. The Apache projects
are characterized by a collaborative, consensus based development
process, an open and pragmatic software license, and a desire to
create high quality software that leads the way in its field. We
consider ourselves not simply a group of projects sharing a server,
but rather a community of developers and users.

74. Vision Statement, Take 2
➡ Community created code
➡ Our code should be exceptional

75. Structure of the ASF - legal
➡ Member-based corporation - individuals only
➡ Members nominate and elect new members
➡ Members elect a board - 9 seats
➡ Semi-annual meetings via IRC
➡ Each PMC has a Chair - eyes and ears of the board (oversight only)

77. Staying true
➡ Policy still firmly in the hands of the ASF
➡ Use outsourced help where needed
➡ Help volunteers, not replace them (if they want to do the work)
➡ Only for administrative efforts
➡ 3 FT sys-admins, 1 PT sys-admin
➡ 1 PT Exec Assistant
➡ Infrastructure itself is a service provided by the ASF

78. Staying true
➡ Board/Infra/etc exists so projects and people don’t need to worry
about it
➡ The ASF exists for the projects, the community and the
membership.
➡ Our “best practices” have proven themselves time and time again to
work.
➡ The board runs the foundation
The PMCs run the projects
(and rarely do the 2 interact)

79. Overview
➡ In general, PMCs are active and healthy!
➡ Lots of releases
➡ Lots of development
➡ New committers and PMC members
➡ New podlings being added (eg: CloudStack)
➡ New projects being graduated (eg: OpenOffice)
➡ ASF continues to be recognized as FOSS leader

80. Protection
➡ Ensuring that IP is checked (oversight and governance)
➡ Tracking and handling any legal issues
➡ Protecting the ASF brand and trademarks

81. 14 Years is a LONG time
➡ Over a decade of declarative discussion and development
➡ We must be doing something right
➡ By maintaining our focus on the right direction - the projects and community
➡ Not all things to all people, and we don’t want to be
➡ Growth, improvement without speciation
➡ The “Apache Way” continues to be a sought-after topic at cons.

82. Open Source Workshop 82
Apache License
 Apache License Philosophy
 To allow the maximum use of our software for any purpose and by all people.
 Give me Credit type
 Requires Attribution via a NOTICE file
 Credits to original author is required, derivatives can sub-license
 No Trademark Grant
 Includes patent grant
 A liberal open source software license
 Business friendly
 Easily reused by other projects & organizations

83. Open Source Workshop 83
Apache Infrastructure
 Provide legal and technical infrastructure for open source software
development and to perform appropriate oversight of such software
 provide a foundation for open, collaborative software development
projects by supplying hardware, communication, and business
infrastructure
 Portal (confluence and moin moin wikis, content management for website)
 Repository for source, SVN and GIT for source control
 Issue Tracking, JIRA and Bugzilla for bug tracking
 Mailing Lists, all the communication
 Also provides integration build infrastructure and many more

84. Open Source Workshop 84
Apache Roles
User Contributor Committer PMC ASF Member
Less Involvement More Involvement
 Apache Contributors/Committers are viewed as individual
contributors, independent of their potential company affiliation
 Individuals are recognized for their contributions and can assume
more responsibility.
 Products are owned by project community.
 Emphasis on community stewardship.
Aaron Farr, http://www.slideshare.net

85. Open Source Workshop 85
Apache Roles Definition (1 of 2)
 User
 Uses the software and provides feedback in the form of bug or feature requests.
 Contributor/Developer
 Contributes to the development of the project.
 Takes the extra steps to participate in the project: Active on the mailing list,
participate in discussions, provide patches, documentation, website updates, new
features, etc.
 Committer
 Committer is a developer that has been given write access to the code repository
and has a signed Contributor License Agreement (CLA) on file. They have an
@apache.org mail address

86. Open Source Workshop 86
Apache Roles Definition (2 of 2)
 PMC (Project Management Committee) Member
 Each project has a project management committee who makes decisions for the project,
such as software releases and community related decisions.
 A committer become a PMC member as a result of their involvement in the community
matters related to the project.
 PMC Chair
 The Chair of a Project Management Committee (PMC) is appointed by PMC Members.
 The Chair is the interface between the Apache Board and the Project. He/she reports status
of the project on a regular basis.
 Apache Software Foundation (ASF) Member
 An ASF member is a person that was nominated by current members and elected due to
merit for the evolution and progress of the foundation. Members care for the ASF itself.

87. Open Source Workshop 87
The Apache Philosophy – “The Apache Way”
 Meritocracy – It’s about what you do, those who contribute decide
 Peer to Peer
 We work with people, not companies.
 Committers and members should hold one another with respect.
 All votes hold the same weight.
 Community over code.
 Consensus decision making
 Most decisions made on mailing list without voting, sometimes by way of lazy consensus
 Typically use Wikis for proposals and design sharing
 Voting rules : Yes (+1) Abstain (0) No (veto or -1)
 A -1 veto requires proposal of an alternate solution
 Open, online communication
 Email lists are preferred form of communication.  The most used and preferred
 Most communication is publicly archived.
 Most lists are open to any subscriber
 Responsible oversight
 Security is mandatory
 Ensure license compliance
 Release only high quality software
 No abuse of Apache brand or community

88. Open Source Workshop 88
What is Karma ?
 A Buddhist/Hindu conceptions of the sum of a person's actions
which dictate his future (lives).
 Now, with regards to open source, your good actions and
contributions come back to you as “karma” or “permission to a given
resource” (e.g. when you become a committer, you receive karma to
source code repository).

89. Open Source Workshop 89
How to Become a User?
 Simply download and use the open source project.
 Report bugs
 Talk to the project community through user mailing list
 Ask questions that will help you build your solution
 Provides feedback to the project
 Usage feedback is important - Examples, here is how we are using the project.
It is working well in these cases and it can be improved in these cases.
 Helps the developers to create software that addresses real use case scenarios.
 Creates a user community who can help each other to use the software properly

90. Open Source Workshop 90
How to become a contributor/developer?
 Actively participate on the project mailing list by answering user
questions, contributing to design discussions, etc.
 Start providing fixes (patches) and small enhancements to code,
documentation, website.

91. Open Source Workshop 91
How to become a committer ?
 Projects recognize contribution and extends the committer role to
high contributors. This means:
 Write access to code and an @apache.org mailing address. It requires a signed
CLA in place.
 One gains committer status through contribution as well as by
gaining the trust of the PMC.
 The criteria is really defined by the character of each project, that is what PMC
believes is important to the project. What is important to that project. Some
general characteristics:
 Dedication
 Attention to code quality and project guidelines
 How well this person collaborates with the rest of the community
 How openly they work

92. Open Source Workshop 92
How to Get Involved with Apache?
 Apache is a non-profit organization run by volunteers
 Apache sponsors can provide monetary support:
http://apache.org/foundation/sponsorship.html
 It is the closest and most direct method for a corporation or individual to support
the ASF
 The ASF provides the infrastructure for the projects - the mailing lists, code
repositories, bug tracking systems, etc. While all of the administrative effort is
currently through unpaid volunteers, financial assistance to purchase bandwidth
and keep servers running is required.
 If interested to get more involved with ASF, start with the above link

Incubator Projects
 Apache projects start as incubator projects that are overseen by
incubator PMC. They are called podlings.
 Once a project demonstrates it can behave as a ‘good’ Apache
citizen, it graduates to a top level project
 It is a worthy and healthy project: diverse and will sustain itself
 It truly fits within the ASF framework
 It “gets” the Apache way
 Useful code
 Working Communication infrastructure
 Active developers
 Dedicated users

122. Open Source Workshop 122
About Apache Incubator
 Apache incubator is the entry path into The Apache Software Foundation
(ASF) for projects wishing to be part of the foundation’s effort.
 Details about Apache Incubator at
 http://incubator.apache.org/
 The Apache Incubator have two main goals :
 Ensure all donations are in accordance with the ASF legal standards
 Develop new communities that adhere to our guiding principles
 Incubator PMC provides oversight for new projects on the following areas :
 responsible for the acceptance and oversight of new products submitted or proposed to
become part of the Foundation
 Ensures that the projects develop products according to the Foundation's philosophy and
guidelines for collaborative development
 Legal – ensures donation are in accordance with legal standards
 Community – helps develops communities that adhere to guiding principles
 Regularly evaluates products to determine if the product should be abandoned, continue to
receive guidance and support, or proposed to the board for promotion to full project status as
part of an existing or new Foundation PMC;

123. Open Source Workshop 123
How to Start a New Incubator Project?
 Detailed Guidelines at this link:
 http://incubator.apache.org/guides/proposal.html#preamble
 Starts with a proposal… Formulate your proposal
 Find a champion. The Champion is a person associated with ASF already and helps move
the proposal forward.
 Identify mentors from ASF or ask for volunteers
 Find a sponsoring organization for the project. This could be:
 The Apache Board
 The incubator
 Another Apache Project
 Post the proposal in plain text in a email whose subject is prefixed with [PROPOSAL] at
general@incubator.apache.org
 Example: [Proposal] Photo Share Project for incubation
 If there is interest, the proposal gets discussed. Expect to revise your proposal with
input from the general discussion. Be Responsive and inviting.
 Once there is consensus on the proposal, post in a email proposal whose subject is prefix
with [Vote].
 Example: [Vote] Photo Share Project for incubation
 When Incubator PMC approves the project, mentors help set up the infrastructure (PRIM) for
the project.

124. Open Source Workshop 124
Tips for Building a successful project
 Make sure there is enough help/resource to jump start and drive the project
 Set clear expectations (pathway)
 Community should understand the purpose and focus
 Don’t worry about duplication
 Be willing to break up
 Open communication - extremely important
 Be inviting and help others to come on board
 Promote the project (blogs, conferences, articles)
 Release often and regularly
 Good documentation and website
 Lower the barrier to entry
 Integrate with other Apache projects if it makes sense
 Watch how other successful projects behave and work
 Use your mentors and the incubator PMC effectively
 Focus on creating a diverse and stable community
 And, be Patient.

178. Creating your project proposal
 Start as early as possible
 The earlier you start working on your proposal the higher is your chance to get
accepted.
 Focus on quality
 Make one good proposal, instead of few half baked ones
 Get involved in the project community
 Subscribe to the development list and discuss your proposal with your mentor and
others on the community
 Be descriptive when writing the proposal
 Describe in detail the idea being proposed, and how is your approach to
implement it.
 Describe the technical details (this shows you have a clear idea of what needs to
be done). Some high level system diagrams is a plus.
 Write a timeline
 Include a detailed schedule of your project

184. How companies use open source
 Internal forking
 Pros
 Quicker to produce fixes for
internal
environments/deployments.
 Cons
 Requires deep knowledge
of the source code
 Can’t easily move to new
releases
 If a must, at least
maintain a internal
branch for the fork

185. How companies use open source
 Partial forking, where
fixes are provided back to
community
 Pros
 Quicker to produce fixes for
internal
environments/deployments.
 Fixes are provided to the
community
 Provide a path for moving
to new releases
 Cons
 Depending on how often
codes are contributed back,
things can get very apart

186. How companies use open source
 Working on the
community
 Pros
 Always in sync with latest
fixes
 Cons
 In general can be a bit
slower depending on the
community
 Can introduce regressions,
which can be mitigated by
test coverage in the
community source
